Question

A soft gel capsule contains 700 mcg of vitamin A.

If a capsule weighs 1.1 g, what percent of the capsule is vitamin A?
Express your answer using two significant figures.

Answer 1

Answer:
To find the percent of the capsule that is vitamin A, we need to divide the weight of the vitamin A (700 mcg) by the total weight of the capsule (1.1 g) and multiply by 100.

First, we need to convert the weight of the vitamin A from micrograms to grams:

700 mcg = 0.0007 g

Then we can use the following formula:

(Weight of Vitamin A / Total weight of capsule) x 100 = % of capsule that is Vitamin A

(0.0007 / 1.1) x 100 = 0.63 x 100 = 63%

So, 63% of the capsule is vitamin A, rounded to two significant figures.
